SAN BERNARDINO, Calif. (AP)  Police say a would-be kidnapper in San Bernardino has been arrested after a nanny fought him off.

Nanny Carmen Perez told KABC-TV (http://bit.ly/1WC785e) that she was pushing a 4-month-old girl in a stroller when a shirtless man she didn’t know headed straight toward her. She says he pushed her to the ground and tried to grab the stroller, but she fought him off.

She says the stroller fell over with the baby still strapped inside.

Three bystanders and a security guard replied to her cries for help and were able to detain the 35-year-old man until police arrived. He was arrested on suspicion of attempted kidnapping and child endangerment.
